The ProHD Report

Fig. 17. DVCPRO-HD comes in both 1080i and 720p flavors. Both formats reduce the bandwidth significantly prior to compression. This diagram shows the 1280x720p60 mode, where luminance bandwidth is reduced to 960 pixels horizontally from 1280, and chrominance to 480. Panasonic claims this is 4:2:2 (and it is if you look at the 960/480 relationship) but, if you compare with full bandwidth 1280/640, it computes to 3:1.5:1.5. DVCPRO-HD reduces the 1920x1080 down to 1280x1080 with color sub-sampling at 640, which becomes 2.7:1.3:1.3 referred to 4:2:2 full bandwidth.

The new HD CODECs

The new HD CODEC technologies comprise MPEG-2 and MPEG-4 in intra-frame as well as GOP implementations, and JPEG2000 only in intra-frame.

Fig. 18. JVC’s ProHD Super Encoder technology, built into the GY- HD250U, is the ONLY HD compression scheme available today capable of delivering the full ATSC 1280x720 bandwidth at the full frame rate of 60p in a 20Mbps transport stream. All this in a HD ENG camcorder with a US list price of $9,995. Color sub-sampling is 4:2:0.
